Rescale
X1 and X2 Fields (Markers Sample mode only)
The X1 and X2 markers are used for displaying and rescaling specific data
values. Assigning values to these fields can be accomplished in either of two
ways. When the field is selected the first time, it turns light blue and
operating the knob changes the value. If the field is selected a second time, a
pop-up keypad appears and becomes the entry method. The X1 field
positions the green X-axis marker and the X2 field positions the yellow X-axis
marker. You can zoom in on the data between the X1 and X2 markers by
selecting the Rescale Field and selecting "between X axis markers." For more
information on rescaling data, refer to the "Rescale Field" section later in this
chapter.

Rescale
The Rescale field is used to scale the sampled states based on the position of
the Y1, Y2, X1, and X2 axis markers. To zoom in on a section of the displayed
chart data, position the markers around the area of interest. When the
Rescale field is selected, the pop-up menu allows you to choose rescaling
between the X axis markers, the Y axis markers, between X&Y axis markers,
Full Scale, or Cancel.
Between X axis markers This selection rescales data on the X axis
based on the X1 and X2 settings. Rescaling places the X1 marker at the
left edge of the display and the X2 marker at the right edge of the display.
Between Y axis markers This selection rescales data on the vertical
Y axis based on Y1 and Y2 settings. Rescaling places the Y1 marker at the
top of the display and the Y2 marker at the bottom of the display.
